 The representative of this Department was the late Marcellus Gardner, 

 who died after a brief illness while the exposition was still in progress, 

 Prof. F. W. Clarke being designated as his successor. The bulk of the 

 collections were sent by the Patent Office and the Geological Survey. 

 The former sent upwards of two thousand five hundred models, which

 number were several of historic interest, including the original models 

 of the Howe sewing-machine, the Morse electric telegraph, and the
